INKING DEVICE FOR LATE-NEWS AND OTHER PRINTING MACHINES.

Substitute for abandoned application Serial No. 42,483. filed July 29,1915. This application filed January 31, 1919, Serial No. 274,165.Renewed February 3', 1922. Serial No. 533,962.

United States, said VVooo residing at the city,

county, and State of NewiYork, said TSBELL residing at Middletown, inthe county of Orange and State of New York, have invented a new anduseful Inking Device for Late-News and Other Printing Machines, of whichthe following is a specification.

This invention relates to an inking mechanism especially adapted forlate news or fudgedevices, but capable of use on other web printingmachines.

The principal objects of the invention are to provide an inking deviceadapted to be run by the fudge cylinder shaft; to provide an improvedarrangement of bearings for the fountain roll in which an inner pairserve to prevent leakage from the fountain and an outer pair of ballbearings serve to support the roll; to provide an improved drive for thefountain roll, and to provide effective means for preventing trouble incase of a paper choke.

Reference is to be had to the accompanying drawings in which Fig. l is alongitudinal section of a preferred form of the invention, showing theink fountain in side elevation;

Fig. 2 is atransverse section of the press on a smaller scale showingthe fudge device in elevation and Fig. 3 is a plan of the fudge andinking mechanism on enlarged scale.

In this case the two main side frames 7 I of the printing press supportas usual the printing couple. The impression cylinder 8 is provided withgears (not shown) driving the gears 40 on two shafts 42 which carry thefudge printing cylinders 43. These are constructed as usual, carryprinting plates or types, and are journalledin side frames 44 mounted ona brace 45 extending between the two main frames 7. Brackets 46 on themain frames of the press serve as outboard bearings for the shafts 42.It will be understood that by means of the usual adjustable gears 40on'the two fudge cylinder shafts, it is possibleto turn the cylinders soas to register with the previously printed page. The side frames alsosupport the inking device for the fudge cylinders and these devices areconstructed to cover the width of a newspaper page,.as for example,seven columns, eight columns, or the like. The fudge boxes are filledwith linotype slugs, one or two columns'wide, and

fastened on the fudge cylinders by the usual means. It will beunderstood that these fudge cylinders can be moved along theirrespective shafts so as to print in any column of the paper,'or twoadjacent ones.

This inking device comprises an ink fountain 47 slidably mounted on theframes 4% and it carries shouldered pins 48- adjacent to the inside ofeach frame. These pins slide in hollow nuts 49 which are threaded insidebrackets 50 on each frame. A helical spring 51 is interposed between thefountain and each inner nut 49 which serves to regulate theftension-ofthe spring. These springs permit the fountain with its roll to move awayfrom the pick up roll 53 in case of apaper choke. The outer nutconstitutes means for adjusting the fountain roll 52 toward and from thepick up roller 53. The fountain is shown as equipped with the usualknife '54 and screw adjustment therefor, but it is provided at the rearside with an additional scraper 55 for preventing portions of a torn webfrom belng wound around the fountain roll. The fountain roll 52' itselfis supported on. ball bearings 57 in the frames but close up to theshoulders are additional capped bearings 58 which serve to prevent theink in the fountain from leaking out into the press.

Each of the fudge shaft gears 41 meshes with a gear 64 on a shaft 65which in turn meshes with a gear 66 on the pick-up'roll 53. The roll 53distributes ink to the form roller 56. Attached to one end of the shaft65 is a worm 68 which transmits motion to a worm wheel'69 on a shaft 70.At the other end of this shaft is a worm 71 which drives a worm wheel72. This worm wheel is fastened to the end of the fountain roll 52 inthe pocket between the capped and ball .or wabble-cam.7 3 fastened- 'tothe second printing couple as may be practicable. It will be seen thatby having thespring seated sliding ink fountain arranged as de-'scribed, it can beadjusted to a working con- 4 tact with the pick uproll 53 in a very convenient way. The pick up roll revolves at pressspeed while the fountain roll revolves continuously but slower and inthe opposite direction to the pi ck-up roll 53. The surface of thepick-up roll and the fountain roll are absolutely parallel but do notcome into actual contact with each other, a very small space,approximately one-thousandth of an inch, intervening, In this way theink is transferred from the ink fountain roll direct to-the pick-up rollwith itsusual vibratingrollers and form rollers. -The two sets ofbearings with which the ink fountain roll is provided constitute animportant feature be.-

' cause the outer ones hold up the weight of the roller while the innerones'serve' to prevent leakagefrom the fountain proper. The method ofdriving the fountain roll by means located between the. inner and outerbearing is important, as well as the location of the ink rollervibrating means in a corv responding space.

Although we have illustrated and described only one form of theinvention, we are aware of the fact that many modificatioiiscan be madetherein by any person skilled in the art without departing from thescope of the invention as expressed in the claims; .-Therefore, we donot wish to be limited to the details of construction herein shown anddescribed or to the particular combinations of parts set forth, but whatwe do claim is 1. The-combination with a fountainroll and its adjustableknife, of an additional scraper on the rear side for preventing por-,tions of a torn web from winding on the fountain roll.

' 2. Ihe combination with a fountain roll, a cylinder, and a formroller, of means for positivelydriving said fountain roll, spring seatedmeans for forcing the fountain roll against the cylinder, and means foradjust ing it to working contact with the cylinder.

3. In a fudge device, the combination of a fudge cylinder, means forrotating it, an ink fountain having an inner pair of bearings: forpreventing the escape of ink, a fountain roll journalled in saidbearings its end studs projecting beyond them, and additionalbearingsen'gaging said studs for supporting the weight of said roll. a I4.
